This is a poorly asked question, probably due to bad supposition of how to
solve a particular problem.

However, to answer the question, wait for the T0IF bit to be set 256 times.
You would end up with the same number of elapsed cycles if the prescaler was
1:8 and you waited for timer 0 to cycle 32 times.

     dbankif  tmr0        ;set banks for access to TMR0
     movf     tmr0, w     ;get the timer 0 value into W
